The LS7222 can be programmed to recognize 3 different codes: one to lock (Arm), one to unlock (Disarm), and one to unlock and trigger an alarm (Duress). Programming is done via the keypad inputs. Any entry from the keypad (when not in the program mode) which does not match one of the 3 programmed codes causes the Tamper output to become active. |
